Enabling TACACS single connect on our 6500 sup720's (SXI code) seem to produce significant delay (~5 seconds) when initially running commands from within a new SSH session, and also periodically the same delay is incurred. This does not seem to be the case on our Supervisor-2 chassis. I assume this is due to the multiplexing occuring; however, I'm not sure why it would occur on some and not all. Thoughts? Thanks!
I have this problem too.
